Transmision on 2000 Hyundai Tiburon

Car will only reverse after shifting 2 drive first? Car has a slow start until it shift 2 second gear n than drives fine?

I think the transmission fluid is low or the transmission has a line pressure problem. It's also possible that the transmission needs a service because the filter is getting clogged.
Get it checked at a transmission shop or a Hyundai or Mitsubishi specialist.
